Building an Android app starts with a well-defined goal and awareness of device variety. Establishing the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release focused and minimizes later rework as the app expands.

Once the foundation is established, focus moves to UI coherence, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics and crash reporting simplify maintenance and iteration after launching on Google Play.
